SPIRAL-DRAIN SMOKE WASHER,

Application filed July 3,

The invention relates to improvements in smoke hydrating and washingapparatus and has particular reference to a structure designed forapplication to any form or type of chimney and adapted to hydrate andeliminate from the smoke all poisonous fumes, sparks, cinders, soot andgases to clarify such smoke and thusly obviate nuisance in congestedcivic centers.

The object of the invention is in the providing of a supportingsuper-structure arranged for attachment to the usual forms of chimneywalls and peripheral rim bodies, having formed therewith a circular andspirally formed reservoir, supporting thereon a dome and smoke deflectormeans, said reservoir having mounted therein a water supply coilprovided with a series of apertures through which water is forced under20 pressure in the form of a doubly deflected spray at a point adjacentthe under outlet edge of said dome to cause the smoke and all itssubstances to pass through said spray, to wash thoroughly and hydratesame after which it passes to atmosphere. Another object of theinvention resides in the providing of a weather vane or spray deflectormeans arranged to control the direction of the forced spray of waterwith relation to the direction of the wind, this object obviates thefaulty feature of blowing sprays under high wind conditions.

In the following I describe a general embodiment of the invention, theparticular features thereof being more clearly defined hereinafter inthe claims.

In the drawing Fig. 1 is a vertical sectional view of a chimney topshowing the relative position thereon of the smoke hydrating apparatusall of that structure being shown in full vertical sectional form; andFig. 2 is a plan cross sectional view of the device con-. stituting thesmoke washer taken on the line 2-2 of Fig. 1.

Similar numerals of reference indicate similar parts throughout theseveral views.

Inthe illustrations forming part hereof 1 designates a chimney top ofthe usual sheet metal form having a peripheral rim 2, to re ceive asupporting member 3 cylindrical in 1922. Serial No. 290,244;

form carrying a channel bead 4 for rigid attachment to-said peripheralrim 2 of chimney 1. Sleeve or member 3 has mounted thereon reservoir 5the bottom of which is diagonally inclined at its bottom in the form ofa spiral basin. or helically' disposed gutter, the upper edge thereofbeing formed in a supporting rim 6 and having a plurality ,ofholestherein to receive supporting bolts 7 carried'by flange 8 forming partof the deflector dome 9.. Said dome 9 is conically crowned to deflectthe smoke and gases from chimney 1, to force same downwardly towardbasin 5.

Said basin 5 or reservoir has mounted therein circular water pipeconnection 10 pro-' vided with a series of apertures 11 to receive waterfrom feed pipe connection 12 and said basin 5 has connected therewith atits lowest point an outlet or exhaust pipeconnection 13 through whichthe exhaust waters and all 70 foreign substances pass to asuitable pointof deposit or reclamation.

Dome 9 has mounted therein a supporting frame 14 provided with a bearing15 in which is mounted a rotating spindle 16 carryingat its upper end aweather vane or wind guide 17, the lower end of said spindle 16 thereofhaving mounted thereon an arm 18 carrying levers 19 and supporting ontheir ends curved plates 20 set normally adjacent spray pipe 10 toprevent the spread of the water spray in the face of a high wind at thechimney top, and to control such hydrating-sprays regardless of winddirection or velocity.

It is obvious that the structural conditions elfected in this assemblymay be varied in many ways without departing from the spirit of theinvention.

What is claimed and desired secured by Letters Patent of the UnitedStates is 1. A device of the character described comprising a structuremountedon and within the exhaust end of a chimney, a spiral water troughmounted on said structure, a smoke deflector dome mounted on saidtrough, a water supply head composed of two circular tubes provided withspray apertures disposed in said trough arranged to project an up sprayof water in the path of smoke emitted from said chimney and directedin-the path 1 of said Water spray by said dome, and Water pipeconnections mounted in said trough arranged to exhaust said trough ofthe used yyater and foreign substance collected there- 2. A device ofthe character described com prising a smoke duct mounted on and Withinthe exhaust end of a chimney, a spiral Water receiving reservoir mountedthereon, a smoke deflector dome disposed across the exhaust end of saidsmoke duct and mounted upon and attached to said reservoir, a Water headcomposed of two circularly arranged pipes having formed therein amultiplicity of apertures adapted to form a Water spray between 7 saidWater head and the peripheral edge of said dome directly in the path ofsmoke emitted by said smoke duct and deflected therefrom by said dome,and exhaust Water pipes disposed in said duct and communicating withsaid reservoir arranged to exhaust the used Watertherefrom.

In testimony whereof, I have signed my name to this specification this26th day of June, 1928.

ALBERT A. MCCANDLESS.
